Hard to disagree with
paco above.
If you're not ready, don't sit them. Don't be bounced into it by a flight school wanting to keep schedule. I've never met anyone who regrets not rushing their exams, but have met plenty who regretted doing them before they were ready.
100% with first time passes should be your aim and nothing less. Obviously a basically impossible target, but even a average 'B' grade student who was several years out of school like me managed all first time passes and an average above 90% so it's certainly doable with work. If you're going into the exam room wondering whether you'll scrape a pass or not, that's not good at all.
As to whether it would affect an airline's view on you. Obviously not. They will not care one bit whether you ground school was six or seven months. I took around two years to do the ATPLs, but I was also working at the same time and took breaks due to Covid. Now... you're flight school and their recommendation might be a bit different and you need to establish that with them. Highly unlikely though IMO.
This is yet another thread reminding us of the perils of the integrated course and the benefits of modular.
